BLE Gateway v4 Firmware

What is the current OTA firmware for the BLE Gateway v4? The changelogs show it as v1.5.12 but my gateway does not detect new firmware.

Please check your current firmware version first. We’ll check the OTA files for you

I was running the beta version so am currently on 1.5.5 but have switched back to stable and want to upgrade to 1.5.12 if possible.
